    Arrow Graphics without BIOS or DOS
    Since my reason for doing assembler is to some day make my own OS, I must be able to draw graphics without depending on BIOS or DOS (as many of you know, the reason BIOS is ruled out is because it causes problems when doing things in Protected Mode, which is the way any good OS must work). Also, I'd like to know how to place code in the boot sector to have my OS load.

    I'd be quite happy just to see it load and put a few pixels on the screen - at least thats a start!

    C'mon, someone must have something to say about this!

    Re: Graphics without BIOS or DOS
    You need to write the VESA driver on your own. Using graphics mode without any interrupts support is more complicated than using the text version. You should go for the ReactOS sources for a VESA driver. Or check http://www.osdever.net for tutorials and documents on it.

    Re: Graphics without BIOS or DOS
    In general, do hardware vendors themselves provide information on how to communicate with their devices or do they solely want to write drivers themselves?
